When it comes to new Macs, it's likely that Apple will want to update its entire range to give them Intel's new Haswell processors. The MacBook Air has already been updated (during WWDC 2013 in June), so we expect that the Retina MacBook Pro, Mac mini and iMac will follow.
Additionally, we know that Apple is planning to release its new Mac Pro and OS X Mavericks by the end of the year, so its October event could be an ideal time to tell us more about when we can expect them to become available.
While not discussed in MacGeneration's article, we've heard that Apple could be planning to update its Apple TV hardware in October, too, so we'll be looking out for that at the special event.
One report has event suggested that an iPhone 6 is on its way, but we are certainly not convinced that this is true.
